Objective To explore the effect of multimodal exercise combined with enteral nutrition dur-ing radiotherapy in the patients with esophageal cancer complicating diabetes.Methods A total of 52 patients with esophageal cancer complicating diabetes in Zhejiang Provincial Tumor Hospital from January to Decem-ber 2021 were selected as the study subjects and divided into the control group(n=27)and intervention group(n=25)by using the random number table method.The control group implemented the routine exercise scheme,while the intervention group was given the multimodal exercise intervention on the basis of routine exercise.The blood glucose metabolism indicators,related biochemical indicators during radiotherapy and the incidence rate of adverse events during exercise were compared between the two groups.Results The levels of fasting blood glucose,random blood glucose and blood glucose before sleep in the intervention group during radiotherapy were(7.79±1.61)mmol/L,(9.47±1.77)mmol/L and(9.97±3.02)mmol/L,which were lower than(11.84±3.47)mmol/L,(14.18±5.42)mmol/L and(14.62±3.83)mmol/L in the control group with statistically significant differences(P<0.05).During the radiotherapy period,the levels of albumin,total protein and prealbumin in the intervention group were(37.96±2.13)g/L,(68.13±5.02)g/L and(232.89±41.11)g/L,which were lower than(36.05±2.89)g/L,(64.96±5.95)g/L and(207.76±47.59)g/L in the control group with statistically significant differences(P<0.05).The incidence rates of adverse e-vents such as falls,hypoglycemia and accidental extubation during multimodal exercise in the intervention group were lower than those in the control group,and the differences were statistically significant(P<0.05).Conclusion The multimodal exercise could significantly improve the nutritional status during radiotherapy in the patients with esophageal cancer complicating diabetes,stabilize the blood glucose level of the patients,and has good feasibility and safety.

Objective:To evaluate the clinical efficacy of nasal pedicle tissue flap based on nasal blood supply in the reconstruction of nasal skull base defects.Methods:A retrospective analysis was conducted on 138 clinical cases of skull base tumors and cerebrospinal fluid rhinorrhea treated at the Department of Otolaryngology, Head and Neck Surgery at Xiangya Hospital of Central South University from March 2017 to March 2023. A total of 79 males and 59 females were enrolled, aged from 8 to 82 years, with a median age of 51 years, including 108 patients (78.3%) with skull base tumors and 30 patients (21.7%) with cerebrospinal fluid rhinorrhea (and/or meningoencephalocele). During the surgery, 88 cases (63.8%) were repaired with nasal septal mucosal flaps pedicled with the posterior nasal septal artery, 14 cases (10.1%) with mucosal flaps pedicled with the anterior ethmoidal artery on the lateral wall of the nasal cavity, 6 cases (4.3%) with mucosal flaps pedicled with the posterior lateral nasal artery on the lateral wall and nasal floor, 12 cases (8.7%) with mucosal flaps pedicled with the anterior ethmoidal artery and posterior ethmoidal artery, and 18 cases (13.0%) with nasal septal mucosal extension flaps pedicled with the sphenopalatine artery or internal maxillary artery. Patients were followed up for 12 to 72 months postoperatively. Endoscopic examination or skull base enhanced MRI was performed to assess the growth and tumor recurrence in the skull base repair area. The t-test was used for statistical analysis.Results:Among 138 patients, primary repair was successful in 133 patients (96.4%), while 5 patients (3.6%) experienced postoperative cerebrospinal fluid rhinorrhea. These 5 patients all underwent nasal septal mucosal flap repair with the posterior nasal septal artery as the pedicle. Complications included 1 case of mucosal flap necrosis, 1 case of mucosal flap central perforation, and 3 cases of mucosal flap survival peripheral leakage, of which were all successfully treated with a second repair.Conclusion:The use of nasal pedicle mucosal flap based on nasal blood supply is a reliable, safe, and effective technique for repairing skull base defects.

Stevens-Johnson syndrome (SJS), also known as the multifactorial erythematous drug eruption, is a class of adverse reactions of the skin and mucous membranes primarily caused by drug allergy often involving the oral cavity, eyes, and external genital mucosa, generally accompanied by fever, and can be life-threatening in severe cases. In February 2022, the Department of Stomatology, the First Affiliated Hospital of Zhengzhou University admitted a patient with huge inflammatory hyperplasia of bilateral lingual margins secondary to SJS. Upon admission, no other obvious symptoms were observed except for tongue hyperplasia. The patient suffered from a severe adverse drug reaction caused by acetaminophen 2 months ago and was complicated by liver dysfunction and pulmonary infection. After 1 month of treatment and rehabilitation, he developed a secondary tongue mass and was subsequently admitted to Dept. of Oral and Maxillofacial Surgery Ward 2, the First Affiliated Hospital of Zhengzhou University. After completing the examination, the tongue mass was surgically removed. After a follow-up of 11 months, the patient's condition was satisfactory and no temporary discomfort was observed. The case of tongue mass secondary to SJS is extremely rare. If a stomatologist encounters a similar case, we should carefully inquire about the drug allergy history and recent medication history, and be alert to whether or not they had adverse drug reactions recently.

As an important part of tumor microenvironment, neutrophils are poorly understood due to their spatiotemporal heterogeneity in tumorigenesis. Here we defined, at single-cell resolution, CD44-CXCR2- neutrophils as tumor-specific neutrophils (tsNeus) in both mouse and human gastric cancer (GC). We uncovered a Hippo regulon in neutrophils with unique YAP signature genes (e.g., ICAM1, CD14, EGR1) distinct from those identified in epithelial and/or cancer cells. Importantly, knockout of YAP/TAZ in neutrophils impaired their differentiation into CD54+ tsNeus and reduced their antitumor activity, leading to accelerated GC progression. Moreover, the relative amounts of CD54+ tsNeus were found to be negatively associated with GC progression and positively associated with patient survival. Interestingly, GC patients receiving neoadjuvant chemotherapy had increased numbers of CD54+ tsNeus. Furthermore, pharmacologically enhancing YAP activity selectively activated neutrophils to suppress refractory GC, with no significant inflammation-related side effects. Thus, our work characterized tumor-specific neutrophils in GC and revealed an essential role of YAP/TAZ-CD54 axis in tsNeus, opening a new possibility to develop neutrophil-based antitumor therapeutics.

Background As an environmental pollutant, 1-bromopropane (1-BP) is ubiquitous in the living environment. However, its health effects on the general population are still unclear. Objective To assess the associations between urinary 1-BP metabolite and blood routine indices in a Chinese community population. Methods A total of 3512 community residents aged 18-80 years from the baseline of the Wuhan-Zhuhai cohort were included in our study. The demographic characteristics, disease history, and lifestyles of the participants were collected through questionnaires. Height, weight, blood pressure, and other anthropometrics were collected through physical examination. Blood routine indicators were tested using an automated hematology analyzer. Urinary 1-BP metabolite N-Acetyl-S-(n-propyl)-L-cysteine (BPMA) was measured by ultra-high-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry. Generalized linear models and logistic regression models were used to assess the associations of urinary BPMA with blood routine indices and the risks of abnormal blood routine indices, respectively. Besides, stratified analysis and effect modification analysis were further conducted to investigate the effects of individual characteristics and lifestyles on the associations of urinary BPMA with blood routine indices. All models were adjusted for gender, age, and other potential confounders. Results The mean age of the study population (30.1% male) was (52.78±12.77) years. The median (P₂₅, P₇₅) level of urinary BPMA adjusted for urinary creatinine was 0.90 (0.50, 1.73) mg·mol⁻¹. In the analysis with target indicator as continuous variable, each 1-unit increase in natural logarithm-transformed urinary BMPA level was associated with a 0.078×10⁹ L⁻¹, 0.031×10⁹ L⁻¹, 0.307%, 3.518 g·L⁻¹, and 2.469×10⁹ L⁻¹ decrease in white blood cell, lymphocyte, lymphocyte percentage, mean corpuscular hemoglobin concentration, and platelet levels, respectively (all Ps<0.05); and with a 0.440%, 1.140 fL, 0.014 fL, and 0.020 increase in hematocrit, mean corpuscular volume, and natural logarithm-transformed levels of mean platelet volume and mean platelet volume/platelet, respectively (all Ps<0.05). The categorical analysis across quartiles of BPMA level showed that BPMA was inversely associated with lymphocyte percentage, mean corpuscular hemoglobin concentration, and platelet levels in a dose-dependent manner (all P_trend<0.05), and positively related to hematocrit, mean corpuscular volume, mean platelet volume, and mean platelet volume/platelet levels in a dose-dependent manner (all P_trend<0.05). Body mass index, smoking, and drinking modified the associations of urinary BPMA level with red blood cell, mean corpuscular hemoglobin concentration lymphocyte percentage, and hemoglobin (all Ps<0.05). In addition, urinary BPMA was associated with an increased risk of abnormal increase in mean corpuscular volume (OR=1.316, 95%CI: 1.171-1.478) and red blood cell volume distribution width (OR=1.255, 95%CI: 1.030-1.528), and abnormal decrease in mean corpuscular hemoglobin concentration (OR=1.200, 95%CI: 1.035-1.392). Conclusion Exposure to 1-BP of the general population is associated with decreased white blood cells and platelets, as well as abnormal change of blood cell morphology or function.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

ObjectiveTo analyze the feasibility， reliability and validity of the disability assessment for dementia scale for the elderly.

Cronbach's α coefficient， Spearman-Brown coefficient， Guttman split-half coefficient and test-retest reliability were used to evaluate the internal consistency of above scales. Criterion-related validity of the scale was analyzed based on MMSE， NPI and PSMS. ResultsA total of 276 patients （95.17%） completed valid questionnaires. The intraclass correlation coefficient of the total score and each dimension were between 0.828~0.976， the Spearman-Brown coefficient were between 0.790~0.917， the Guttman split-half coefficient were between 0.812~0.857， and the Cronbach’s α coefficient were between 0.737~0.886. The cognitive function dimension score was positively correlated with the MMSE score （r=0.948， P<0.01）， the mental behavior symptom dimension score was positively correlated with the NPI score （r=0.893， P<0.01）， and the daily living ability dimension score was positively correlated with the PSMS score （r=0.997， P<0.01）. The dimensions scores were positively correlated with the total score of the scale （r=0.634~0.841， P<0.05）. ConclusionDisability of dementia assessment scale has good feasibility， reliability and validity， which is a reliable tool to assess senile dementia and disability.

In recent years, bacterial antibiotic resistance is becoming a huge threaten for human health. It′s getting even more serious after biofilm formation. In addition to physical and chemical factors such as barrier function and microenvironmental changes, the regulation of some genes in biofilm also specifically improves the level of antibiotic resistance. There might be a common regulatory mechanism between antibiotic resistance and the ability of biofilm formation. Type Ⅰ clustered regularly interspaced short palindromic repeats (CRISPR) system can affect the acquisition and spread of antibiotic resistance. The effect varies with species, evolution process and environmental pressure. Recently, it has been reported that type Ⅰ CRISPR system could not only regulate biofilm formation, but could also participate in the interaction between bacteriophages and biofilm. It might become a breakthrough point in the study of phage therapy. This article reviews the situation of antibiotic resistance in recent years, the new progress of biofilm-specific antibiotic resistance, and the effects of type Ⅰ CRISPR system on biofilm formation and antibiotic resistance, so as to provide new ideas for the prevention and treatment of bacterial infection.
